IS THERE any evidence that the blood volume is regulated? Or, put more specifically, is there any evidence that signalling systems, nervous or hormonal, respond to changes in the optimal level of blood volume and bring into play mechanisms that restore the blood volume to optimal levels? By examining what is known of the factors controlling blood volume we may see if any answer can at present b...

This paper introduces a new acceleration technique for ray casting type volume rendering called IsoRegion Leaping. A factorization of the sample composition equation leads to our new algorithm which is based on homogeneity inside a volume. We create an IsoRegion data structure to help identifying homogeneous voxel cubes, which is independent of the viewing parameters and shading conditions, thu...

(CITC), under the conditions of the reported typical experiment (Table 1), contained a total of 4.428 g of protein in a volume of 1,220 ml. The final eluate, in a volume of 274 ml, contained 1.121 g of protein. This represented, in effect, a net removal of 74.7% of proteinaceous material, while effecting a volume concentration of 4.45 X. There was a concomitant increase in the CF antigen titer,...

the management of water table is introduced as one of the major parts of the solutions in water resources management. this method could play a significant role in protecting water resources, increasing irrigation efficiency, preserving nutrients in soil, and protecting the quality of surface downstream, and as well, of groundwater. towards this end, a laboratory study has been done on the effec...
